Comparative morphological study of spinal cord of siamese twins

Considering the rarity of occurrence of such anomalies of human development, like siamese twins, and a few reports of a descriptive nature in the available literature that would have dealt with these studies, we performed anatomical and histological, histochemical and morphometric study of spinal cord siamese twins (thoracopagus) in a comparative perspective: right - left. Found that significant differences in the structures of the spinal cord cytoarchitectonics the left and right of the fetus thoracopagus person we have not identified. However, slight differences in morphometric parameters observed at the level of the cervical and lumbosacral bulges. The results, in our view, not only complement the knowledge in human teratology, but in neuroanatomy as a whole.
